Dermatosis con infiltrados plasmocitarios, ¿secundaria a queratosis actínica? / Dermatosis with plasma cell infiltration, secondary to actinic keratosis? / Dermatose com infiltrados plasmocíticos, secundária a queratose actínica?

Las dermatosis plasmocitarias son un conjunto de enfermedades inflamatorias poco frecuentes, cuyo diagnóstico definitivo se realiza mediante el hallazgo histopatológico de un infiltrado dérmico de células plasmáticas policlonales sin una causa subyacente demostrable. Presentamos el caso de una mujer de 89 años que desarrolló en la evolución de una queratosis actínica un infiltrado plasmocitario denso. Hasta esta publicación no se han encontrado reportes de casos de dermatosis plasmocitaria secundaria a queratosis actínica.

Cutaneous plasmacytosis is an uncommon cutaneous disorder, the final diagnosis of which is done when cutaneous polyclonal plasma cell skin infiltrations without underlying proven causes are found. The study presents the case of an 89-year-old patient with actinic keratosis who developed dense plasma cell infiltration. There were no case reports of cutaneous plasmacytosis secondary to actinic keratosis in literature until this study was published.

Relation of Immun Function State with Patient of Invasive Fungal Infect that Peripheral Blood Appear Plasmocyte / 中华医院感染学杂志

OBJECTIVE To know the immunate function state when patients with invasive fungal infection appearing peripheral blood plasmacyte.METHODS Twenty cases of invasive fungal,bacterial infection and normal concentrate blood smear if apper plasmacyte and quantity;adopt flow cytometer technology,nephelometry were used to detect lymphocyte subpopulation,immunoglobulin level.RESULTS Concentrate blood smear find plasmacyte in 15 case invasive fungal infect patient,commonly bacterial infect only 1 case.nomal had not find.invasive fungal infection patien lymphocyte subpopulation CD3+:(50.2?6.1)%,CD4+:(23.6?3.5)%,lower than normal CD3+:(66.8?8.0)%,CD4+:(35.2?5.1)%.But CD8+:(33.9?4.5)%,CD19+:(34.2?7.0)% there were hinger than normal CD8+:(26.5?6.5)%,CD19+:(12.0?4.9)%,CD16/56+ parting(18.8?5.1%,18.2?7.0%).There ware no marked difference in two group of invasive fungal infect patients and normal immunoglobulin level parting:IgG 8.35,7.72 g/L,IgA 1.59,0.99 g/L,IgM 1.20,1.07 g/L.CONCLUSIONS Invasive fungal infect patients when concentrate blood smear find plasmacyte,are found with low immune and blood serum immunoglobulin level with NK cell quantity no obvious change;but CD19+ lymphocyte quantity increase.

The Effect of Interleukin-18 on Airway Inflammation in Asthmatic Murine Models and Its Mechanisms / 华中科技大学学报（医学）（英德文版）

In order to investigate the effect of interleukin-18 (IL-18) on airway inflammation in asthmatic murine models and its mechanisms, BALB/C mice were randomly divided into three groups (n=10 in each group): group A (control group); group B (asthmatic model group); group C (IL-18-treated group). The asthmatic model was established in groups B and C by respiratory syncytial virus (RSV) killed by ultraviolet. Saline solution (0.1 mL) and IL-18 (0.1 mL, 1 μg) were intraperitoneally injected respectively in groups B and C at 7 time points (day 1, 2, 7, 8, 9, 21, 22). The number of eosinophils (EOS) and plasmacytes in the airway was observed. The levels of inter-feron gamma (IFN-γ) in bronchoalveolar lavage fluid (BALF) were measured by ELISA. The results showed that symptoms of asthma in group C were more severe than in groups A and B. In group A,there were no EOS and plasmacytes in the airway submucosa. The number of EOS [15±3 (average cell counts per microscopic visual field, the same below)] and plasmacytes (10±2) in group B were increased significantly. However, the number of EOS and plasmacytes in group C (6±2 and 2±1, re- spectively) was decreased significantly as compared with group B (both P<0.05). The levels of IFN-γ in groups A, B and C were 31±3, 40±5 and 63±5 pg/mL respectively, and those in group C were sig- nificantly higher than in groups A and B (both P<0.05). It was suggested that the mechanism by which IL-18 inhibited the airway inflammation in asthmatic mice might be contributed to the fact that IL-18 could induce the induction of IFN-γ.
